Sony Reader store customers will have to transfer their library to Kobo, a competing yet compatible service that Sony partnered with. Existing Reader store credits will also get transferred to the new Kobo account, while any pre-orders for forthcoming titles will be cancelled.

The best bet in the long run is to ditch the Sony Reader for an alternative reader found on smartphones, tablets or Amazon’s Kindle devices. Here are the ways people get e-books now:

Buy: Amazon remains the biggest and most successful seller of e-books. You don’t need a Kindle device to get e-books from Amazon. The company makes Kindle apps available for pretty much all smartphones, tablets and computer platforms. The aforementioned Google Play Books and Apple iBooks are also alternatives, but bear in mind, there really are no devices that are compatible with them and not Amazon’s content.

Borrow: Most major public libraries in the U.S. now rent e-books. If you are a card-carrying library member, you can download e-books to your smartphone, tablet or Amazon Kindle device (or app). Many public libraries partner with Overdrive, which offers its e-books through an app app that is available for a wide range of devices.

Rent: Sites such as Scribd, Oyster and Entitle Books offer a subscription service, where you can rent two or more e-books a month for a flat fee of around $10 a month. But these services are largely targeted at those e-book readers who have tablets. Scribd and Entitle apps are available for smartphones and tablets; at this time, no dedicated readers work with the services.
